At what rate in watts does the jet airplane in Problem 3 radiate energy in the form of sound waves?
The intensity of the sound wave from a jet airplane as it is taking off is 1.0 × 102 W/m2 at a distance of 5.0 m.
What is the intensity of the sound wave that reaches the ears of a person standing at a distance of 120 m from the runway? Assume that the sound wave radiates from the airplane equally in all directions.
